RULlNG-MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 619,717, dated February 21, 1899. Application filed $epte1nber 2, 1896- Serial No. 604,607. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES BURROWS, a citizen of the United States, and a resident of Schenectady, inthe county of Schenectady and State of New York, have invented certain new and useful Improvements in Ruling- Machines, of which the following is a specification.

My invention relates to improvements in machines for ruling fiat paper, and relates more particularly to improvements on my invention set forth and described in Letters Patent No. 568,236, issued to me and dated Sep-v tember 22, 1896, for ruling-machines; and it consists in the combinations of devices and elements hereinafter described, and set forth in the claims.

The object of my invention is to provide a positive means by which the pen-beam may be nicely adjusted in direction transversely to that of the direction the carrying-apron of the machine is run and then be secured from being accidentally moved longitudinally in either direction. I attain this object by the means illustrated in the accompanying drawings, forming a part of this specification, in which- Figure 1 is an elevation illustrating my invention, and Fig. 2 is a front elevation with a part shown in section.

The same letters of reference refer to similar parts throughout both views.

In the drawings, A is a portion of the framework of the ruling-machine, and B is the end less apron.

O is the pen-beam, and E is an adjustable standard (one of the two) for supporting the adjustable bearing G of the end pintle of the pen-beam O. The said adjustable standard and means for adjusting the said bearing G are fully described in my above-mentioned Letters Patent No. 568,236. I will therefore only briefly refer to the principal parts of the same, so as to connect the improvements in this invention with the parts employed in my former invention.

The standard E, by its smooth-bore sleeves b 1), holds in place the horizontal sleeve F, which is integral with and mounted on the screw-threaded vertical post F and calculated to be elevated or lowered accordingly as the revolving finger-nut F is revolved.

The adjustable bearing G has its arm G contained in the horizontal sleeve F and is held in place adjusted to by means of the split sleeve portion, provided with lugs and the clamping bolt or screw F The end pintle C of the pen-beam O is preferably made and secured with the ends of said pen-beam (but one shown) in the manner generally practiced by the trade. In the drawings the pintle O is shown to have its inner end portion provided with a journal 0, of less diameter than the body of said pintle, working in sleeve 0 having with it the flange-collar c and screw end 0 screwing into the end of the pen-beam C. This journal c of said pintle is shown to be held from moving longitudinally by means of nut c and jam-nut c screwing on the screw-threaded stem portion of said pintle-journal, as shown. This end pintle O is provided with a fingerhead 0 for convenience of revolving it at will in either direction, and it has between the sleeve 0 and fingerhead 0 a screwthread 0 The bearing G of this end pintle C of the pen-beam has heretofore been in the form of an annular wall unbroken in its continuity and having in its bore a screw-thread corresponding with the screw-thread 0 provided on the pintle C. These plain screwthreaded bearings, with their unbroken walls, by use become worn, as do the screw-threads C of the pintle, and allow a gradual though slow change of the place of the pintle in its bearing, and thereby effect an endwise movement of the pen-beam, which gradually becomes so great as to cause the points of the pens to strike the paper carried by the apron at a greater or less distance from the points originally had and intended to be preserved in all the sheets ruled. This change is a serious defect which my present invention is intended to remedy. In this invention the pintle-bearing G is slit from one side thereof, and preferably from its lower side, and this bifurcated wall has integral with it the lugs gg, one of which, as g, is perforated with a plain hole, and the other, as g, is provided with a screw-threaded perforation. A clamping-screw G passing through the plain perforation in lug g and having its screw-threaded stem working in the screw-threaded perforation of lug g, serves as a means for contracting the diameter of the wall of the bearing G when the said clamping-screw G is turned in a proper direction for drawing the lugs g g toward each other. This split pintle-bearing is provided with an internal screw-thread S, which corresponds with the screw-thread 0, provided on the pintle C, so as to nicely work in the same when the latter is revolved by its finger-head C in either direction. When this pintle C is revolved in one direction, the coacting screw-threads C and S will operate to move the pen-beam longitudinally away from the said bearing G, while when revolved in the opposite direction they operate to carry the said pen-beam longitudinally toward said bearing G, and by such movements as may be necessary to be made an operator may readily adjust the pen-beam in either direction, and thereby carry the point or points of the pens to particular points on the paper to be ruled and carried by the apron beneath the pens. WVhen the pen-beam has been adjusted ready for working the machine, the operator will tighten the clamping-screw so as to draw the lugs g g toward each other. The split walls of the said hearing will be tightened on the screw-thread portion of the pintle and held so tight on the same as to prevent a relative movement of the pintle and its bearing with each other, and thereby cause all movements between the pintle and the pen-beam to occur at the joint between the journal 0 of the pintle and the sleeve 0 and thereby positively prevent the pen-beam shifting in either direction in relation to the apron carrying the sheets of paper beneath the pens and in direction transversely to the direction of length of said pen-beam, and also prevent any vibration or shake of the said pen-beam when the screw-thread on the pintle becomes loose by wear.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. I11 a ruling-machine the combination with a pen-beam, a pen-beam pintle 0 provided with the screw-thread C and journal 0 of less diam eter than that of its screw-threaded body and having its outer end portion screwthreaded and provided with nuts 0 and 0 a sleeve 0 receiving the said journal portion of the pintle and provided with flange c and the screw-threaded end portion 0 screwing into the end of the pen-beam, of the internal screw-threaded pintle-bearing G having a split wall and lugs g g each perforated and one having its perforation screw-threaded, and the clamping set-screw G whereby said pen-beam may be longitudinally adjusted in either direction, at will, and be secured from shifting with permission for free vertical oscillation substantial] y as and for the purposes set forth.

2. In a ruling-machine the combination with vertical standard E provided with sleeves b 1), vertical post F working in said sleeves and provided with screw-threads and integral with the horizontal sleeve F having a split side wall and a screwing device for contracting said wall at Will, of the screw-threaded bearing Gr having a split wall and a screw clamping device for contracting said split wall, at will, and made integral with arm G which is adjustably secured within the split wall of the said horizontal sleeve, a pen-beam, sleeve (3 screwed into the end of said penbeam, pintle 0', having journal 0 of smaller diameter than its body and provided on its larger portion with screw-threads C, which are received in the screw-threaded bearin g G and having the finger-head 0 whereby said pen-beam may at will be both longitudinally and vertically adjusted and secured as set, with permission for free vertical oscillation, substantially as and for the purposes set forth.
